Belated guiding questions on Noble and Layton

I'm a bit late on getting you these questions, but here they are in any event in case you haven't gotten to your reading yet.

How do Noble and Layton *together* argue how the engineering profession evolved? What were the major signposts each used? What were the different historical steps? How has engineering as a "profession" evolved over time, as described by each?

Gieryn describes the boundary work that goes into the practice of science and technology, and outlines both the characteristics of boundary work itself and gives appetizers to his later chapters of various boundary work cases (which we won't read here, but I recommend you do read at some point, particularly the one on the NSF/NSSF).  How might the tool of "boundaries" be helpful in thinking through Noble and Layton's histories of the engineering profession?

See you Thursday.  We're beavering away on your essays...
